Facebook CEO Mark Zuckerberg has been showing off what he dubbed the company’s mobile VR future.

Talking to the Oculus Connect developers conference, Zuckerburg demonstrated a prototype stand-alone VR headset and he mentioned the world “affordable”.

The main feature of the new prototype standalone headset was its positional tracking. In fact it was a modified Rift with a compute module embedded into the back. This positional tracking technology allows the headset to understand where it is in physical space and adjust the onscreen content.

Positional tracking allows you to walk through an experience and see it from every angle. Zuckerberg said development is still incredibly early, but that it’s on the product roadmap.

Positional tracking has previously only been available on the major high-end VR headsets including Oculus’s Rift headset, the HTC Vive and PS VR, but with this announcement Oculus is closing the gap between mobile VR experiences and their high-powered counterparts.

Positional tracking on mobile is a technology it is rather hard on the battery and it was a difficult problem to fix. There were no details given a potential launch date either.

A Chinese audience was amazed when Facebook CEO Mark Zuckerberg hosted a Q&A in Mandarin. Zuckerberg gave a 30-minute question and answer session in fluent Mandarin at a Q&A and apparently, it was not about ordering a sweet and sour pork and rice, or asking where the loos were and was pretty challenging. He was talking in Beijing because if he had talked in Mandarin on a American University campus they would have just thought he was insane and locked him up.

The Facebook chief executive is known to have been studying the language for several years, having mentioned his interest in Mandarin in an interview with Oprah Winfrey in 2010. To be fair Mandarin is a pretty tricky language and standing up in front of kids at Tsinghua University in Beijing and talking about social notworking must have been hard. Commenters on the post described his efforts as "seriously impressive" and "pretty cool."

Zuckerberg said there were three reasons why he had chosen to study Mandarin. First, because his wife is Chinese and her grandmother only speaks Mandarin so he began learning to be able to communicate with her. Second because China is an influential country and he felt studying the language would help him better understand its culture. And finally because Mandarin is really hard and he likes challenges.

A judge in Iran thinks that it would be a wizard wheeze to try social notworking God Mark Zuckerburg for invading the privacy of Persians with his Facebook operation. Of course if they ever get the guy in the dock the court promises him a fair trial. The Judge has already dubbed him a Zionist even though he is not a practicing Jew, so we can see Zuckerberg checking his passport to see if he can have his day in court.

Apparently the trail is motivated by a couple of complaints by individuals who cited that there were unspecified privacy concerns which were related to Instagram and WhatsApp. Iranian official Ruholla Momen-Nasab mentioned to state news agency INSA, "According to the court's ruling, the Zionist director of the company of Facebook, or his official attorney, must appear in court to defend himself and pay for possible losses."

Yeah we can see that happening Ruholla, there are shedloads of people of Jewish descent who are just queuing up to be tried by a court which makes those in the US look sane by comparison. To make matters worse it appears that one side of the Iranian justice system does not know what the other side is doing.

An Iranian prosecutor Wednesday denied reports that a local judge ordered Facebook founder and CEO Mark Zuckerberg to appear in court. Shiraz Chief Prosecutor Ali Alghasimehr was quoted by the official IRNA news agency as saying Zuckerberg has not been summoned to court and Facebook-owned applications Instagram and Whatsapp remain permitted.

Ruhollah Momen Nasab turned out to be an information technology official with the paramilitary Basij force. That is not to say that they don’t have the power to order someone into court, but it does look less likely.

Facebook is already officially banned in the country, along with other social websites like Twitter and YouTube as well as their mobile apps. However, many Iranians use proxy servers to access banned websites and applications, and some senior leaders such as Foreign Minister Mohammad Javad Zarif are active on Twitter.

Facebook CEO Mark Zuckerberg made $3.3 billion last year by exercising stock options in his social notworking site. The windfall saddled Zuckerberg with a huge tax bill, but I don’t imagine he is too upset – at least he is paying tax.

It is the second straight year that Zuckerberg has realized a huge gain on the holding that he has accumulated in Facebook since he started the company in 2004. Last year he made $2.3 billion off his stock options. However he has now apparently exhausted his supply of stock options after exercising 60 million of them last year a price of 6 cents per share. He then sold 41.35 million shares for $55.05 apiece in December, primarily to pay for his tax bill on the gains.

Zuckerberg and his wife, Priscilla Chan, also donated 18 million Facebook shares to a Silicon Valley nonprofit. The December gift, then valued at nearly $1 billion, landed the couple at the top of The Chronicle of Philanthropy's annual list of the most generous Americans.

Zuckerberg still owns 426.3 million Facebook shares currently worth $25.7 billion. The stock has more than doubled in value during the past year.

The man behind the most antisocial of “social” concepts, Mark Zuckerberg, is no longer among the world’s top billionaires.

Much like his rapid ascent to the highest echelons of the rich and untouchable, Zuckerberg has seen Facebook hit many a roadblock as of late. As a result, Facebook shares dropped to just over $20 last week, setting a new record low for the company.

The Bloomberg Billionaires Index says Zuckerberg is currently worth $10.2 billion, which is so sad it brings tears to our eyes. The number is based on 503.6 million shares of Facebook, 60 million options with exercise price of six cents per share and measly $150 million in cash and other liquid assets.

Egyptian revolutionaries have invited Facebook founder Mark Zuckerberg to visit the freshly democratized country in an expression of gratitude for Facebook’s role in the January revolution.

They have asked the country’s Minister of Culture Imad Abu Ghazi to formally invite Zuckerberg, who has already expressed pride in Facebook’s role in the popular uprising.

Analysts agree social networks and online communication played a crucial role in rallying the lethargic masses against regimes in Egypt and Tunisia, as well as the rest of the Arab world.

Cairo University professor Sherif al-Labban believes Facebook provided Egypt’s youth with an unprecedented way to gather momentum for the revolution which toppled the Mubarak regime, which had been in power since before Zuckerberg was even born.

The FaceMash.com web address that landed Facebook founder Mark Zuckerberg in trouble as a Harvard University student has been flogged for more than $30,000.

Zuckerberg was a Harvard student in 2003 when he made a FaceMash.com website at which people could compare pictures of coeds at the college and rate which was "hotter". The site was shut down by Harvard administrators unhappy with the stunt. Zuckerberg dropped out of Harvard and started Facebook the next year.

FaceMash was the inspiration for Facebook social notworking site and was memorialised in "The Social Network" film about the birth of Facebook.The buyer of web address remained secret, but Flippa went on record saying that it wasn't anyone from Facebook or Sony Pictures, which made "The Social Network" flick.
